If you ride lot, specially on smaller slopes, then sure you want Fintecs.
Intec will wear quite rapidly, making holes of moving pins oval which allows more forces to plastic which finally will break.
I used to switch Intec every year or every second year. Now with Fintecs since they come out.
Only mod i did is replaced that silly plastic "bearing" around pins with metal ones few years ago after that all works better than ever.
